STEAM-SIREN.

To all whom tt may. cfm-cem: Be it knmm that I, EMIL HoENow, citizen of the Uliited States, and resident of Glen'- dale, borough of Queens, Qucensand State of'New York, have 1nvented certain new and-useful Im rovements in Steam-Sirens', .of which .the fol) 4. specification.

sectional View ofmy improved siren. Figi'. 2,

My invention relates to steam siren and the object is -to provide a whistle of `this class which will be more perfect in operation and more durable, and to simplify the construction of the valve sc thatthe same may be easily opened under a high pressure of steam.

. Referring to the drawlngs which form part of this specification, Figure 1, is 4a vertical is a cross secitiona'l View of the sameon ine x-- of Fig.' 1, and Fig. 3, a cross section 'by a screw thread at C.

through the valve and casing on'line Z- J of Fig. 1.

, A indicates a flange A at its lower end tube which is provided with 4a by which it may be -attachedto a steam conduit.

B, indicates the bell or horn ofthe whistle which is screwed on to the circularcasing C,

securedto the'tube A, by. a screw joint at C2, and thereby serves to hold the disk D, firmly in place across the steam passage by clamping itbetweenthe lower end of thecasing C and the ribs T of the casingA', as shown,-

forming a joint at D below which a conduit for steam is formed as indicated by the dot-4 cylindrical recess -Formed 'in the bottom of the disk D is a D, in which a piston E is fitted, which is made integral with the valve stem. Et, and onthe lower endof said valve stem is located the main lvalveEZ whichseats .on the tubeA at A3. The valve stem E- is provided witha central passage 'E3 which extends throughout its length, and located in the lower part thereof is a valve stem F having a valve F which is adapted to close the lower end of the passage E3. The valve F is held in position by a spring G which embraces lits lower end as shown, and in turn rests upon a bridge piece H provided with ,openings H for the'flow of steam therethrough.

' v'The lever Iis fulcrumed on and heldin place by the bolt J .as shown, and o ne end passesjthroughan opening 1n the casingand engages .with both the inain valve stem E and the 'auxiliary valve stem F, andis adapted to Specification o f Letters Patent.

operate the same as will more fully appear hereinafter.

'On the upper en'dA ofthe disk D is a dcpression D3 1n the bottom of which is located some Babbitt' or similar bearing metal D? and supported by the same is an anti-friction bearing ball of metal K, which serves as L, which is screwed -to and sup orted on the spider-likehanger M, at M. isprovided with an opening at its center. which-is threaded to engage witl1 tl1e ivot post N, which is secured in'its place Iby a ook nut N. The lower end of lthe pivot vts over one side of the ball K, which.` acts as a ivot 0n which-the hangerv4 the cylin er L rotate lwithin the casing C. The upper end` of the pivot post N is' )rovided with a depression in which the ball O, -iits and is held by the lower end of the screw P, which is held in the spider casting C3 ofthe casing C, as shown. The spider-C3 forms openings C4 to allow the steam to pass to the steam ell. f

It will benoticed that the and the screw P and the balls the wearing parts of the bearings may bc easily removed and replaced by new parts at a very'small expense, and. that the other operating parts may he. readily removed for inspcctimi orrepairs, which is a valuable feature of the construction.

The casing C is provided .with openings formed at an angle to the radii of said casing. The openings' L which are located in the cylinder li are also set at an angle to posite to the angle of the openings in the casing (l, and this fornmtion is such that the -steam in llowingthrough from theI annular chamber Q to the openings C?, will cause the 'cylinder L to rotate very rapidly, 'thereby alternately opening and closing the passages formed by the'opcnings C5 andi] and settingI up sound waves.

In operating the device, the'steam 1s admitted at R, and by operating the lever I, the auxiliary valve F is forced away from its seat `inthe stcm E and the steam .flows through the passage E3 above the piston E, which is almost as great in area as the area of the main Valve E2,-and thereby relieves the pressure vfrom the main valve E2 almost' entirely, so that a further movement of the he hanger ost N is provided with a depression which the .radii of the cylinder and at an angle op,-

i and() and lever I, Will cause' the main valve to be opened by reason of the contact ci' the part l with the valve Stem at E, while the auxiliary valve F fis held open by the extreme end of the lever I? .The steam flows through the main valve and the passages S-S formed by the casing and valve stem, to the passages indicated by v dotted 'lines A2 and formed by the ribs T, T, l0 in thevc'asingi A and the dish D and casing C, as'will bef'olfearlyunderstood, to the annular ,qnamberQ,through the openings G5 and L s.and C4 tothe horn and thence to the atmosffphere.; The steam in iiowing through the )le said vopenings isfree to iiow under the hanger M, so that the saine is balanced, and the pressure on the pivot ball bearing is thereby relieved.. Byreleasing the lever I, the auxiliary valve will immediately clo'se and trap a' 'small amount of steam above the piston-E, so that the main valve will close very ily- `which prevents the said valve from wearing out or hammering.

thus described niy invention, what 2-5' I cla'ii'n as new and desire to secure by Letters .1Patent, i s- 1. A steam siren comprising, a tube hav.

ing a valve' controlled passage and an annular chamber, the inner wall whereof is circular 3 0 and provided with openings set'at an angle 'to the radii of said inner wall; a hollow open .'ended cylinder to fit Within said chambered end having openings in the side wall correvl`gsp0nding to said openings in the inner wall of l`fs`aid chamber and inclined at an angle op- A'posed to the angle of the openings in said inv n. er wall; pivotal inountings Jfor said cvlinder `consisting in a pivot post the ends whereof are cupped, anti-friction balls located in the 4Q cupped ends of said post, a spidcihhlie hanger f engaging said cylinder and threaded on said 0st, suitable locking device for locking said anger on said post when adjusted, a spider lwasting provided with a threaded perforafeg'tion, a 'screw in threaded engagement with `said perforation in said spider casting and ihavhig a cupped end vto seat the upper of said balls; and suitable means for opening and closing the valve controlled passage.
